City of Ottawa has a dataset with park pathway links. These are typically narrow grassy polygons of public land between houses that connect roads to roads or roads to parks. Usually they contain pathways and some of these pathways are not yet in OSM as they can easily get overlooked in the imagery.

This project aims to map all these pathway links as well as landuse polygons when applicable.

Take a task, open it in JOSM. Look through the pink links. If you see one that doesn't have a pathway in OSM - check if the pathway exists in the imagery (usually it does), trace and tag it.

(optional) Switch to pathway-links.osm layer and merge landuse polygon to the working layer. It's helpful to see a strip of green on the map between houses where there is passage. No need to do that if there is park/grass there already.

Once you make sure there are no missing links in your task - upload the data and take the next task - step 4.
